Fast determination of compatibility of virtual machines and hosts

摘要

A method and system of determining compatibility of a virtual machine or virtual machine disk file with a host, including a storage host, is disclosed. A lookup matrix (104) is created (steps 158 and 182) to provide a fast compatibility lookup for a group of computing objects and a group of hosts. To create the lookup matrix (104), computing object properties (steps 152 and 172) are retrieved from each of the plurality of computing objects (VM1-VM5). The computing object properties include resource requirements of each of the plurality of computing objects. Further, host properties are retrieved (steps 154 and 176) from each of the plurality of hosts (H1-H5). The method further includes creating a plurality of host logical groups (steps 155 and 178) of a subset of the plurality of hosts (H1-H5) having substantially same host properties and creating a plurality of computing object logical groups (steps 153 and 174) of a subject of the plurality of computing objects (VM1-VM5) having substantially same computing object properties. The lookup matrix (104) provides answers whether each member of a selected computing object logical group (VMG) can be transferred to each member of a selected host logical group (HG).
